conjunctiva

Phthalylsulfacetamide (Tamid) is a sulfonamide antibiotic used for topical application to the skin and the conjunctiva.

Emedastine (LY188695) is a second generation, selective histamine H1 receptor antagonist with anti-allergic activity. Emedastine reversibly and competitively blocks histamine by binding to H1 receptors, thus blocking its downstream activity. As a result this agent interferes with mediator release from mast cells either by inhibiting calcium ion influx across mast cell basophil plasma membrane or by inhibiting intracellular calcium ion release within the cells. In addition, emedastine may also inhibit the late-phase allergic reaction mediated through leukotrienes or prostaglandins, or by producing an anti-platelet activating factor effect. Upon ocular administration, emedastine causes a dose-dependent inhibition of histamine-stimulated vascular permeability in the conjunctiva. Emedastine does not affect adrenergic, dopamine, or serotonin receptors.

Emedastine Difumarate is a selective histamine H1 receptor antagonist with anti-allergic activity, prescribed for allergic conjunctivitis. Upon ocular administration, emedastine causes a dose-dependent inhibition of histamine-stimulated vascular permeabil

Oxybuprocaine hydrochloride (Oxybuprocaine HCl), a local anesthetic, is used especially in otolaryngology and ophthalmology.

Fluorometholone (Fluoromethalone) is a corticosteroid, most often used after laser-based refractive surgery. It is marketed under the brand names FML (Allergan) and Flarex (Alcon). Fluorometholone acetate ophthalmic suspension is indicated for use in the treatment of steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the eye.
